LUBRICATOR.

SPECIFICATION forming part 0f Letters Fatemi: No. 690, 1 14, dated December 3l, 1901.

Application filed April 9, 1901. Serial No. 55,018. (No model.)

To all whom it may concern.'

Be it known that I, JAMES MAOKENZIE, residing at South Hadley Falls, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

My invention relates to improvements in automatically-feeding oil-cups; andithas primarily for its object to provide an oiler of this character in which the feed members can be quickly adjusted to discharge a greater or less amount of oil and in which the filtration of the oil is effectively accomplished automatically and without necessity of stopping the feed.

My invention also comprehends in its complete make-up a novel correlation of two or more offtake or feed pipes of different sizes coperatively arranged with a single cup and each having` independent siphoning members of predetermined capillary action, whereby a number of offtake or lubricant-conveying pipes for carrying off different quantities to diderent bearing parts of a machine or machines is provided in a simple and inexpensive manner.

My invention also embodies a novel correlative arrangement of a single oil-cup, one or more otakes or discharge-pipes having capillary-acting means for taking up and discharging the oil, and a special means for interlocking the cup with the otake pipe or pipes.

In its moresubordinate nature my invention consists in certain details of construction and peculiar combination of parts, all of which will hereinafter be first described in detail and then specifically pointed outin the appended claim, reference being had to the accompanying drawings, in Which- Figure l is a view of an oiler constructed in accordance with my invention, the same being shown with three independently-operating offtake devices. Fig.' 2 is a vertical section of the same. Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 2. Fig. 4 is a view illustrating the manner in Which the siphon members are adjusted. Fig. 5 is a detail view of one of the Siphon-Wicks and its adjusting member. Fig. 6 is a detail view of a modified form hereinafter referred to.

Referring now to the accompanying drawings, in which like characters indicate like parts in all the figures, l designates the cup or vessel for contain ing the oil and which comprises the metal base l, the detachable metal cap lb, and the glass body 2, held in place by the annular flange 1c in the base member and a pendent iiange l1 on the cap or top lb. The base has one or more screw-threaded apertures, three being shown, a central one, 3, and two side ones, (indicated by 3fL 3b.) .The several openings may be of like diameter to receive offtake or feed tubes of like capacity. In the drawings the several openings 3 3 3b are shown of different sizes, the central one, 3, the largest, the one 3a the next largest, andthe one 3b the smallest, it being understood that in practice the feed or offtake pipes 4 4fL 4b, fitted in the respective openings 3 3 3b, are connected with bearings requiring different quantity of lubricant. The pipes 4 4a 4b each have an externally-threaded portion 4 to engage the openings 3 3a 3", and the two pipes 4 4b extend nearly up to the cap-plate lb. The center pipe 4 is of a length to extend up through a central opening o in the cap-plate, and the projecting portion of said end is externally threaded, as at le, to receive the lock-nut 6, Which holds the capplate lb and the glass body 2 in proper position as well as providing a simple means for quickly removing the said cap-plate 1b when access to the interior of the cup and adjusting of the VWick members are desired.

Instead of locking the cap-plate on the cupbody, as shown and described, the central pipe 4 may also stop short of the top of the cup, as shown in Fig. 6, and its ends have an internal thread 3X to receive the threaded spindle 6X, formed on the lock bolt or nut 6, and, if desired, the cap lb may be provided with openings 5 5 over the pipes 4a 4" to receive the handle ends of the Wick-adjusting members (see Fig. 6) presently again referred to.

As is clearly shown in Fig. l, each offtakepipe joins with a valved extension 7 7.

Within each of the pipes 4 4 4b is an independently-acting wick 8 8, of a suitable permeable material-mineral Wool, for example--or any other material that acts to conduct the oil up into and down through the pipes 4 4a 4b by capillary attraction'and also at the same time act as a straining medium.

It will be noticed, particularly by reference to Fig. 3, that the wicks for the several pipes 4 4a 4b are of sizes to correspond with the diameter of the pipe with which they cooperate.

I am aware that oil-cups having offtakes having oil-carriers that convey the oil by capillary attraction and discharge it by a siphoning action have heretofore been provided. So far as I know the quantity of oil to be fed is governed by means of valves or gates at the discharge end of the offtake-pipes or by squeezing or twisting the wicks. `Adjusting the feed in the aforesaid manner has been found not to produce the results desired, for the reason that valves or gates at the discharge end frequently cause the iow of oil to stop by clogging, and the twisting or squeezing of the wick also falls short of what is desirable for a proper and regular feed., as it is difficult to properly adjust the wick by squeezing or twisting it, as such adjustmentof the wick causes it to cease to properly ilter the oil, and in consequence clogging and stoppage are thereby produced.

To provide for conveniently adjusting the wicks 8 without in the slightest interfering with their capillary or iltering qualities, I use a stouty spring-wire member 9, the lower end 9iL of which is made fast to the lower extremity of the long arm 8ay of the wicks, as clearly shown in Fig. l, and the upper end ofsa'id member 9 extends up beyond the top of the pipes 4f1L 4b and ends in a handhold 9, that may be bent over, as shown in Figs. 2 and 5, or may extend straight up under the Vopenings in the cap-plate l, as illustrated in the modified' form. (SeeFig. 6.) The'short arm of the several wicks drops. down adjacent the pipes with its lower extremity rubbing the bottom of the cup, so that they will take up the oil as long asa drop remains within the cup. As the central pipe 4 has its upper end constructed to interlock with the` means for holding the cap-plate 1b down, said pipe has a lateral tubular extension 1f,through which the wick for said pipe 4 and its coacting adjuster 9 is passed.

From the foregoing description, taken in connection with the accompanying drawings, the manner in which my improved oiler operates and its advantages, it is thought, will be readily understood.

To make any one of the pipes feed slowlysay a few drops per hourthe long arm of the wick is set to be just long enough to create a siphoning action, and to obtain a very rapid feed the long arm of the wick is correspondingly lengthened, which operation can be effected by removing the cap-plate whenl the form of cup shown in Fig. 1 is used or by manipulating the adjusters-through the openings in the cap-plate when the formy of cupv shown in Fig. 6 is used.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

An oil-cup, comprising in combination with the cup, and including the removable cap, a pipe extending up into the cup, its upperend being threaded, and having a lateral tubular extension, a clamp-nut engaging the cap and threaded end of the pipe, and a wick held in the cup having its long end extended into the tubular end of the pipe, and means for moving one end of the wick up and down in thel
